Organic petrology, maturation, thermal and burial history analysis, and hydrocarbon generation and migration modeling of the Saudi Arabian paleozoic petroleum systems
… allowing for calibrated models of temperature history. Sensitivity analyses for maturity support the view that thermal boundary conditions and Hercynian uplift and erosion did not greatly influence the Paleozoic petroleum systems. Second, a 3-D basin model was constructed using major geologic …

Seismic stratigraphy and burial history for source and reservour prediction in the Luderitz basin, license blocks 2412B and 2413B, offshore Namibia
… of the study area. The modelled thermal history suggests that potential Lower Cretaceous source rocks may have generated petroleum only at locations of thick overburden, such as the base of slope location.

Taphonomy of a Lance Formation(Maastrichtian, WY) Dinosaur Bonebed with a Focus on Tooth Traces
… fluvial bonebeds, including differences in pre-burial history, depositional mechanism, subenvironment, and post-burial history.</p> <p>Although only a few Rose Quarry bones show evidence of tooth traces, a similar nearby bonebed contained a tyrannosaurid metatarsal (HRS13997)that possessed …

Provenance, redox conditions, and diagenesis of shales in Chang 7 member of Upper Triassic Yanchang Formation, Ordos Basin, China
… to decipher provenance, redox conditions, and burial history of shales in Chang 7 Member of Upper Triassic Yanchang Formation, Ordos Basin, China. The first paper discusses the origins of single-channeled, vertical, sinuous, and calcite-bitumen-filled cracks in the shales. Results show that in …

Origin of Green Shales in the Devonian Swan Hills Formation, Alberta, Canada
Throughout its growth history, the Devonian Swan Hills Reef Complex at Swan Hills has been subjected to variably long episodes of subaerial exposure, storm events, strong wind, oceanic currents, base level fluctuations and/or a long post-depositional burial history. For nearly sixty years, several …

Manganese mineralization hosted by the Rocky Gap Sandstone in Bland County, Virginia
… The stratabound nature, regional extent, burial history, and proximity to fractures on the crest of an anticline indicate the deposit at the Stange Mine was formed by ground water at the interface between deeply-percolating, oxygenated meteoric water and reducing manganese and iron …

Structural diagenesis of bed-parallel and bed-normal fractures, Cretaceous Crato Formation carbonate rocks, NE Brazil
… caused by increasing overburden related to burial, next by jointing caused by decreasing overburden related to uplift and finally by dissolution along joint walls. Porosity was reduced by cementation of fractures, both during and after opening, and later enhanced by dissolution of cements …

Pore pressure, and the interdependency between lithology, porosity, and acoustic log response targeting the Vaca Muerta Formation
… such as hydrocarbon maturation and variations in burial history will cause velocity response to follow unloading paths, not solely loading. To capture the excess pressure generated, pore pressure can be estimated from wireline sonic logs using a modified Bowers approach. This method uses an …

Thermal history model of the Williston Basin
… of the Basin was significant to the thermal history of the Basin at its very beginning stage. However, most of the anomalous heat would have dissipated before the deposition of Bakken Formation 363 Ma ago. The heat flow history of the Basin was probably a steady-state condition after the …

Structure, Stratigraphy and Hydrocarbon Potential of the Colombian Caribbean Margin and Tsunamigenic Hazards in the Western Caribbean and the South China Sea
… recent, tectonic, structural, and stratigraphic history of the deepwater portion of the region, with an emphasis on hydrocarbon exploration potential. I also characterize the submarine landslide related tsunami hazard of the western Caribbean region and for the South China Sea. In Chapter 2, I …

Natural Gas Generation Potential of the Wufeng-Longmaxi and Niutitang Shale Formations, Sichuan Basin, China: Insight from Hydrous and Anhydrous Pyrolysis
… main stage gas was generated early on during burial history. The majority of source rocks showed very low S1 + S2 peaks from Rock-Eval pyrolysis, suggesting no residual gas generation potential based on conventional thermal cracking mechanism. Source rocks which underwent hydrous pyrolysis …

Relative timing of dolomitization and silica cementation in the Cambrian Potosi and Eminence Dolomites in the Illinois Basin, USA
… been undertaken to reconstruct the complex history of post-depositional subsurface physical and chemical alteration (diagenesis) of the Potosi and Eminence Dolomites. Analysis of the Potosi and Eminence Dolomites was completed at two locations within the Illinois Basin, which included: (1) …

Geodynamic evolution and petroleum system of Abu Gharadig Basin, North Western Desert, Egypt
… processes that occur during the long basin history by the application of Petroleum System Modeling. Applying basin modeling makes it possible to evaluate the four dimensional controls on source, reservoir and seal rock distribution, the master tectonic mechanisms, as well as source rock …

Palynology, palynofacies and hydrocarbon potential of the Cretaceous rocks of northern Egypt
